What to look for in knowledge base software

The best knowledge base software for you depends on how your business works, not only on where a product sits in the list. Before you shortlist the top-ranked options, check for:

An editor that makes articles quick to write and easy to keep current
Search that finds answers however people phrase the question
A public help centre, an internal wiki, or both, with permissions
Feedback and analytics on what people search for and fail to find
Integration with your help desk and chat, so agents can share articles
Owners, review dates and version history for each article

How to use this ranking

Start with the top 10, then narrow down with Best knowledge base software by category further down the page, which ranks the same feature inside each kind of software. Read the reviews on each profile, and ask vendors to show you the points above with your own data before you decide.

How is this list of the top knowledge base software worked out?

TrustList ranks every product that offers knowledge base, whichever software category it is filed under, by its rating, how many reviews it has and how complete its profile is. No one can pay for a position in this list. Where few products have reviews yet, profile completeness carries more weight, so treat the order as a shortlist to check rather than a verdict.

Is the top-ranked product the best knowledge base software for everyone?

No. A small team, a growing business and a large enterprise need different things from knowledge base software. Use the checklist above and the rankings by category to find the best fit, and give most weight to reviews from companies like yours.

How often does the ranking change?

The order is recalculated as new reviews arrive and vendors update their profiles, so the list you see is the current one.
